IAMES F. SEERY, OF NEWr YORK, N. Y., ASSIGNOR TO THE EMPIRE HYDRO a CARBON COMPANY, OF NEV YORK.

HY'DRocARBoN APPARATUS.

SPECIFICATION forming part of Letters Patent No. 400,959, dated April 9, 1889.

Application led May 24, 1887- Serial No. 239,196. (No model.)

To all whom, it may concern.-

Be it known that I, J AMEs F. SEERY, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvement in Hydrocarbon Apparatus, of which the following, taken in connection with the accompanying drawings, is a full, clear, and accurate description.

The object of my invention is to produce improvements in hydrocarbon furnaces or apparatus; and it consists, first, of a movable steam coil or superheater for superheating steam capable of being raised above the burner or lowered to its normal position at will.

lt also consists, secondly, of an auxiliary circulating-coil connected with the lower and upper parts of the boiler, and serving as an auxiliary heater to heat the water in said boiler.

My invention also embraces a deilectingplate and flue for deflecting the flame under the boiler, and also protecting the boiler and preventing injury to the iron.

It further consists in an oil-tank suitably connected with air-chamber and pump for forcing oil into the injector, and provided with a safety-pipe adapted to prevent explosion. These various parts are also united and combined in various combinations.

In the drawings, Figure l is a sectional view of my improvements. Fig. 2 is an end view of the furnace portion of my apparatus, the outside pipes being severed at the line Fig. l. Y

Similar letters indicate corresponding parts.

My improvement is made as follows:

A represents a steam-boiler provided with a dome, B. l

C is a brick-work in which the boiler A is secured. This brick-work O is provided with the arched opening C', opening into the vertical passage O2, and also provided with the flue or pipe D, one end of which opens into the outer air at C3 and the other end intothe vertical passage at D. The vert-ical passage D is continued in horizontal position under the boiler A, forming the passage E, which enters a vertical passage, E on the other side of the boiler. The brick-work at one side and top of the vert-ical passage D is formed into a curved or slanting surface, forming a deflecting-plate, F.

G is the injector or burner composed of the pipe G, which supplies said injector with 5 5 live steam from the dome B, the pipe G2, which supplies the injector with air from the interior passage, C2, and the oil-pipe G3, leading from the oil-reservoir O, hereinafter described.

G4 is a mixing-chamber where the steam, after passing through the pipe G to superheating-coil G5, where it is superheated, is mixed with the air and oil flowing from their respective pipes, the superheated steam passing into the mixing-chamber G4 through a suitable nozzle, g. (Shown in dotted lines.) From the mixing-chamber G4 the mixed oil, steam, and air passes to the burner-head H.

The oil-pipe G3 and superheating-coil G5 are furnished with suitable valves and cocks for regulating the supply to mixing-chamber G4. The steam-pipe G is also provided with a valve and stop-cock, G6, placed between the s11perheating-coilG5 and the mixing-chamber G4, in order that the steam in said pipe G may 75 act as a cushion or buffer against the pressure developed in t-he mixing-chamber. p

The superheating-coil G5 is so pivoted at h as to be capable of being raised or lowered at will by the action of the lever L, connected 8o with said coil at I, said lever being supported in suitable pivots at I.

Mis an auxiliary coil placed in the passage C2, and connected by two horizontal pipes passing through the brick-work O with the boiler A. The lower horizontal pipe, m, is connected by the pipe N with the lower portion of the boiler. The upper portion, m', of the coil M is connected with the Lipper part of the boiler by the pipe N', these pipes having suitable valves and stop-cocks.

` The oil-reservoir O, designed to be placed underground, is furnished with pipe o, leading to air chamber or receiver R, which is connected by the pipe p with an air-pump. 95 Not shown in the drawings.) Said oil-tank O is also provided with apipe, P, leading up and opening into the air. The pipe P is formed With a horizontal portion or joint, P', which is designed to be filled with rosin. The oilroo tank O is also furnished with a small stopcock, S, to drain the oil-pipe G3 of oil when its valve is closed.

The operation of my invention is as follows: The boiler A being supplied with water, the stop-cocks in the pipes N and N are opened, allowing a circulation of water through the coil M. At the same time the valves in the oil-pipe G3 and the superheating-coil pipe G5 are opened, and oil is forced by the action of the air-pump from the oil-reservoir O into the mixingchamber G4, where it is mixed with air coming through the air pipe or passage G2. The burner-head II being lighted, the operation commences. The heat generated at this burner-head l-I passes upward through the center of the coil Bil', and is deflect-ed by the delecting-plate F `under and through the boiler A, as shown by the arrows, an auxiliary draftbeing created through the air-passage D. It will thus be seen that the coil M receives and utilizes the heat in the first instance, and prevents the waste of heat which would other wise occur, and also generates steam very quickly. in said coil. This steam passing through the pipes `m and N to the upper part of the boiler aids greatly in quickly converting the water in the boiler into steam. being` formed in the boiler passes from the dome B through the steam-pipe G to the super]mating-coil Gwherc it is superheatcd, and thence passes through the mixing-chamber GA1 to the burner-head l'l in conjunction wit-h the intermingled air and oil. If it be de sircd to heat the coil M to a higher degree, the superheating-coil is raised, as shown in dotted lines, by means of the lever L, whereby it is brought more directly into contact with the flame, and,when desired, can be returned to its normal position around the burner-head. The deflecting-plate F serves to receive the first impact of the flame of the burner, and thus protects the iron of the boiler from any injurious action.

lt will be seen on inspection of the drawings that when the supply of oil to the injector G is stopped by stopping the action of the airpump any oil remaining in the injector will d `ain out by releasiu g the ai r-p ressure through the stop-cock S. It is designed to place the oil-reservoir O at a distance from the furnace and below ground, as a precaution against fire and explosion. As an additional precaution,

the oiltanlc O is provided with the pipe P and its resin-filled joint I, and if too much heat is generated said rosin will be melted,

Steam thus allowing the vapors of the oil to have free vent to the open air.

By drawing the supply of hot air from the fire-box above the burner any unconsumed combustible material which would otherwise be wasted is drawn in with the air and again brought into the mixing-chamber.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. In combination with the tire-boX of a furnace, a vapor-burner located therein, and a pivotcd coil of pipes forming a superheatcr for steam surrounding the burner, and means whereby said coil may be raised above the said burner at will, substantially as and for the purpose set forth.

2. In combination with a furnace having a hydrocarbon-burner, a superheating-coil surrounding the burner and beingpivotally connected to its supply and exit pipes, a lever connected at one end to the coilpipe, and a fulerum for said lever, the free end of the lever being made to extend outward and adapted for prehensiou, as and for the purpose set forth.

The combination, in a furnace provided with a iirebox having an arched top forming a deflecting-plate, of a stcamgenerating coil placed below said arch, a vapor-burner, anda superheatiug -coil surrounding the burner, substantially as and for the purposes set forth.

a. In combination with the fire-box of a furnace having a suitable burner and an arched or curved deflecting-plate, a draftfpipe opening into the 'lire-box above the dellectingplate, a steam-generating coil placed below the delectingplate and above a burner, and a superheating-eoil surrounding the burner, substantially as described.

5. In combination with the lire-box of afurnace, a hydrocarbon-lnirner, a steam-superheating coil, a mixing-chamber, pipe for supplying oil to said mixing-chamber, an airpipe leading from the lire-box above the burner and connected to the mixing-chamber, and a steam-pipe connect-ed tothe superheating-coil and mixing-chamber, forming an injector, all substantially as shown and described.

In witness whereof I have hereunto set my hand this 12th day of May, 1887.
